Figs. 18 are end view and plan of cover for mestcnwheel.

The 1in-turc of my invention consists, first, in certnin improvements in the construction of the fra-mes for hnrvesters geared with n bevel master-wheel end first pinion and a. spur second wheel nnd pinion, seid freine consistu ing of n cast metallic plate, having nbox* shaped standard for the' cmnklieering of the crankshaft, and a. partiel cese for the second wheel and pinion, and bearings foiall the ione nn-ls for the gear-shafts cast with. it, :ind ham ing combined with it si'iiteble covers and plates in snch n manner as to completely incase the gearing of the machine in tivo separate cavi ties, one of which contains the masteravheel and pinion and the other the second wheel end pinion, and, ii desired, toi'orm n third onvity or box for carrying tools or ext-rn. pieces,

whereby I obtain n very light, stron g, and cheep cased frame for the machine, in which all the bearings und gear :nc weil protected from dust :nid dirt.

My invention consists, secondly, in the use of a. brncephite sind ot' n peculiarlyformed clamping-piece, to strengthen the connection between the brace-bnr and conplingbar in the coupling-heme, whereby the strength and sti it ness of the coupling-frame nre considerably increased with ont little expense.

My invention consists, thirdly, in thc novei mode of securing the finger-bar in the heelA shoe, and in the novel inode of controlling the rolling motion of the Enger-bnr, by means oi' which the driver can vary the angle of the teeth with the ground, as desired.

My invention, consists, ionrthly, in forming notches of n. V-section in the front edge of the finger-bar, sind in making n backwardsloped fece on the finger to fit into seid notch, whereby the strength and stiji'ness of the connection between the inger and iingei-bar are greatly increased.

My invention consists, ii'lthly, in the novel construction of the grain-shoe for the finger ber, mid in the novel construction ofthe springrnnner for the sanne, and in the novel inode of seeming the tmcker-rods in the saine, whereby liessen the cost of construction end the dfi-nger of .clogging 0r mingling the grain or grass at the grain end of the iingerbnr.

My invention consist-s, sitthly, in the novel construction of the connection between the pinnen-rod end the knifebm head, whereby I obtain e very cheap end solid connection, in which there is little liability to any cramping, heating, or looseness luider :my movement of the nger-ber or under the most rapid movement.

My invention consists, seventiiiy, in the novel arrangement of thc shipping-lever and mechanism for throwing the machine in and ont of gear, and in the use of a. broad treadle board pivoted on rods pivoted on the frameplate, and resting on one side on the shippinglever, and so :n'rnnged that the feet of the driver, when on his sont, press on the treadleboard, and thus hold the machine in gear, whereby I obtain en easy footrcst for the driver, and insnreihc throwing of the ino/chine ont of genr in ense the driver steps or is thrown from the machine, thus lesscning the liability to accident in case of stepping or being; thrown in front of' the finger-bar,

To enable others skilled in the art to maire and use my invention, l will proceed to dnscribe its construction and operation.

The construction of the frame for my 1unchine, both for a front and rear eut machine, is shown in detail on Sheet 3.

In the frame for the front-cut machine, Figs. i3, 14, and 15, A represents the cast metallic base-plate, which constitutes the body or plat forni of the traine, and which may he casi solid or with an open-work, as shown iu lfig. 13. At the front part of this plate is cast the boxshapcd standard yi, which carries the crank end of the crank-shaft, and which has east al its lower end the shield N, as shown. 'ihr partial case li for the second wheel and pinion is cast at the rear end of the plate, and the cavity 52 for the bevel-pinion, lange 53 for the attachment of the inasterwheel cover, and bearings G4 64 65 6G 67 67, for the driving'- shat, second shaft, and crank-shaft, are all cast on this casting in their appropriate places, as shown. The front of the case h is closed up by a plate of sheet metal, G8, shown in de taehed view in Fig. 15, which fits in lips h' It' formed at the edges of the ease, and the top is covered by the cast cover C D, which is Limited by hinges to the plate A. The lower part of the master-wheel, the first pinion, and thc second sha-ft are incased bythe cast cover g, which is bolted on the under side of the plate A, and the cast cover B is placed over the top of the master-wheel, and fits down on and is secured to the llange 53 on the plate A.

It will be seen from this description that all the bearings of the shafting are cast on the casting of which the `plate A is a part; consequently there can be no deran gement of the alignment of the bearings when once fitted. It is also seen that the gear will be wholly iucased in two cavities; one formed by the cases q B and plate A, and containing the bevel master-wheel and first pinion and' the other formed by the partial case la, plat-e GS, and cover C D, and containing,r the second wheel and pinion.

The details of constmction of the frame may be somewhat varied to meet different require ments of construction without chan ing; the general plan-as, for example, in the rame i'or a rear-cnt machine, as shown in Figs. 1G, l?, and 1S; the bearings (l5 6G 64 64, for the second shaft and driviugshaft, are formed below the plate A, instead oi' in it, as shown in Fig. 14, so that the said shafts can be laid in their bearings from above, instead of being placed on below, and to coliform to this change the neck 57 of the cover g is shortened up, so as to (it up to the bearing G5; the senuciu-.ular part 56 is cast on the cover B, to cover the second shaft and bevel-pinion, in place of' cnsting,l the cavity 5L (sce Fig. 14) in the plan` A; the semicircular part 59 is cast on the rover C l) to tit up to the partG, and complete the corel' over the second shaft, and the cover Sl is provided to cover the driving-shaft. Flaug'es are cast around theA part 56, to secure theY cover I. (which fits over the ilango 53, in this ense) lo the plaie .\4

[t is obvious that, under the arrangement shown in Fig. 1G, the (uwer g or its equivalent` could be castwith the plate A, if desired.

The sheet-metal plate j is secured in the standard i by means ot' inside flanges and rivets, ns `shown in Figs. 13 and 16, or in any other Sulnhh: manner; and tln: over E is hinged on the plate A, as shown in Figs. lll and 17, thus forming' a convenient tool-box i'or the machine.

The longue l" is secured to the plate A, as shown, and ihe side plate k is casi nl the grain side of the plate A, to strengthen the salue, as well as to forni a side board for the traine.

The driving-shaft H is secured on the bear ings 64 G4 by suitable covers, as shown in Fig. 7, and has at its ends the driving-wheels G G, which cause the rotation of the shaft Hthrough the ordinary ratchet-andpawl connection. Y

The bevel master-wheel 35 is secured on the sha-ft H, and meshes into the pinion 34, which is loose on the second shaft 33, which shaft is secured on the bearing 65 and G6, as shown. The end of the pinion 34 is made with a clutch face, and a clutclrwheel, 36, is arranged to slide, but not to turn, on the shaft 33. A colv lar-groove is cut in the clutch-wheel 36, and in it sits the arin 37, which is fixed on the pin 3S, in thecover B, and which is made in a U form at the lower end, so as to fit in the collar-groove in the clutch-wheel 36. The lever 39 is fixed on the pin 38 ou the outside of the cover B, and is supported by a spring, 40, lixed in the plate A, as shown in Fig. 7, from which it is evident that if the lever 39 be pressed down by the foot of the driver on the treadlearin 43 at its end the clutch -wheel 36 will bc forced forward to clutch with the pinion 34, thus eonimiuiieating' motion from the masterwheel 35 to the shaft 33; but if no pressure be exert-ed on the lever 39 it will he held up by spring' 40, thus keeping,r the machine out of gear. The second wheel 32 is fixed on the shaft 33, and has two circles of cogs, 3l and 32, of different diameters, out on its fai n.. 'lhe crankshaft 2S is secured in the bearings (i7 67, as shown, and has secured on it one ot' the spur-pinions 30 or 70, depending on whether a fast or slow `speed is required. The pinion T0, when not in use, is hung on a pin, 7l, in the case )1., as shown in Fig. 13, and when the driver' desires to change thc speed he throws up the cover C D by turning' bach the button 73 (see Fig. l) and turning the cover on its hinges 5l 5l, when the plate 68 can be lifted out, and the pinion 30 taken oit' the shaft 2S, and the pinion 70 put on, as is readily secu. The crank-wheel 29 is fixed on the shalt 2S, and has the crank pin 73 fixed in it. as shown in T,

The coupling-traine O l Q, by which the linger-bar is attached to the main frame. is :n

ltztclied to the frame nit the points 75, 55, end 74, (see Fie. 14,) these points of ntteeinnent being in line with each other, the forward point 75 being; on the shield N, in front of the erenhwheel 29, the point 55 being in the renr of the crank-Wheel on the stenderd i, and the point 7 4, also in the rear of the crank-wheel, being on the cese k, es shown.

The coupling-frame consists of the eouplin gbar Q, brace-ber P, and second coupling-bar O, as shown in Fig. S.

The clamping -shoe a, provided with the lower flanges a a?, which sit on earch side of the brano-ber P, and with upper iianges al al, which sit on eaeh side of' the eouplingbar Q, is pleeed et the crossing' of seid bers, as shown, end the brace-plete b is riveted et one end to the bracefbnr P, et seine dist-ence beek of the clamping-piece a, and is fastened on top of the oonplingbalr Q by al bolt or rivet, 7-7, which passes through the hars b, Q, end l), end the pieoe e, end binds them together, from which it is Seen that the plete b and clampingpiece a ect es breees to prevent any movement of the bnr Q on the ber P. The end of the brace-bnr P is fastened to the moin frame by n, pin, 7S, (see Fig. 6,) passing' through the ing 74 (see Fig. 14) end e hole in the ber into the ense h, sind the end of the bnr Q is secured by the pin 50, which passes through the lug 55 into the standard (See Fig. 14.) The second coupling-bar O is riveted to the bnr P, end is bent at right angles :it the other end, so als to enter a hole in the bearing 7 5 on the shield N, es shown in Figs. 1 and S. The spring S0 is placed around the pin 50, and has one end errenged under the conplin g-berQ, sind th'other end arranged against the stenderd i beyond the pin 50, and sewes to snstein e portion of the weight of the coupling-freine and heelshoe. The heel-shoe T (shown in Figs. 3) is formed from wrought-iron or steel, and has an erin nptiuned at each end to form points of ettecinnent for the coupling-frame.

In order to obtain bearings of snicient snrfnce in seid nrnis to aliord good \vea.ring-snrfeces for the pins on the coupling-frame, the hushed bearings 1 1 are driven into said arms in thefposition shown, thus giving e long socket for4 eaeh couplingfrznne pin, sind avoidingl the dztngero' cutting into said pins by pivoting' them in a thin plete, :tnd making it very easy to remove the old bearings end repln-ce them by new ones whenever they become worn, so as to t badly.

The pivotepins 49 49, on the eouplingfrome P Q, ere formed by bending the ends of the breoe und eonpling-borsforward, and drawing and shouldering down the pins on their ends, es shown in S, so that ssiid pins form e solid part of' the eonpling-ilmne, :ind there is no danger of their working' loose, as is the cese with a pivotbolt in :in eye in the ends of the brace or coupling' ber, which was the former .inode of construction, While this inode oieon struction is much cheaper than the old e011- struction.

The heel-shoe T is Secured on the coupling fritmePQ by bringing the bea-rings 1 l in front of the pivotpins 49 49, and then moving; the shoe back in e manner similar to 'that of henging :t door, thus making' it very to innig nud nnhztng the ing'erbar.

The finger-ber R is mede of a. broad flat ber of steel, and has the groove 2 formed in its upper face, which groove serves as e bed for the knifeber 19 to slide in. The rear sind inner end oi the finger-ber R is worked ed' into a,- seinieironlnr forni, and grooves znc out in the upper lmnd lower feces oi' seid bnr, parallel to I(nid just in front of seid rounded end, so als to form a hin ge-pin, 4, on the reztr edge of the finger-ber, es seen in end view in Fig. 3, Suid pin being of e length eqnnl to er n, little greeter then the width oi' the shoe T.

A groove of e forni correspondingwith the forni of the pin 4 is nia-de :dongl the beek erm of the shoe, so that by sliding the bnr R into the shoe T the pin 4 will enter the groove, and n. hinge-joint be thus effected between the finger-bar und shoe. The pin 3 is fixed in the shoe T, and projects through at slot in the finger-bnr R, thus serving to prevent the bnr from sliding from the shoe find bracing the bnr in the shoe. The end arm 6 of the linger-bnr is mede of sheet metal, riveted on the under side of the linger-bar, and bent over into the form shown in Figs. 3, so es to cover the end ofthe knifebar from dirt or grass. The spring l0, or any equivalent therefor, is arranged nnder the erin 6, es shown, or beck under the finger-ber, if preferred, and serves to keep seid lier turned up, when not forced down by the driver, end the hook 12 is inserted in the shoe T sind projects over erin 6, thus preventing the ingenbar from being thrown up too far by the Spring l0. The standard 7 is secured to the shoe T directly in front of the :trui 6, and lies pivoted on it the lever 8 which works on the arm 6, and, when turner np und :t little past e vertical position, strikes on the pin il, thus forcing and looking down the erm 6, and consequently giving a downward pitch to the fingerbar. The erin 11 is secured, with the stand ard 7, to the heelshoe T, and, when the eonp lingfrznne is raised by the driver, it strikes under the bmeebnr l), thus enabling the dri ver to mise the grain end ot' the iingerber. The upper end oi' the lever S is mnneeted by si. rod, p, to the lower omni: u of the doublecrenk shaft m n, which is arranged in n stende ard, 79, fixed on the tongue F.

The upper erenk in is connected by rod Z to the leverz, pivoted to the side plete k, and standing' at the side of the drivers feet, so that by Working the lever Z lie een operate the le ver S and vary the angle of the lingers with the ground in a manner readily seen. The knife-ber 19 has the knives o o (inode either :ill from one piece of plate-steel, its shown, or in sections in the ordinary manner) riveted on its upper side, ns shown. The knife-bnr rune in the slot in the Finger-ber R, sind the knives slide on the face of seid bei', so that there is no space left-:between lthekniie und knife-:bor

ond lthe Iingeribnr :to Agather dirt or grossi,4 [ind the top S of the knife nndiing'cr-boris nearly smooth, and hns nothing onivhich the `bnttsoi" The pieces 25, 25 keep the knifebur down on tlieiiiigerbgil,

the grass :ire Ylisible to catch.

:ind the .knitefbarshmrk 1-3 is secured onlthe knives r, as shown. A circuler hole isiorined in this shnnk,.lmving 4its front endbeveled,

and inrit is placed ithecireulzngnnt1 0, which has a. flange, 17, to pievient iL from sliding through the shank, there iL is retained bythe piu 1S, ns shown in Figs, 4.

The hole 62 in, the nut `lfis ,made ysquare at. thecenter and is rounded' on the upper and' lower sides, nud the 4pin :15 of the pitrnn-n is inode square, so as to just :it in the hole 62, from which it is seen that the connection hetu'cen the ,pitinan and knife-bnr will adjust itself to the .increments of Lthe :pitmanend finger-bnr, and lto 4the -rolling nioin'on ,of -thel fingerhar around the hinge-joint 4 with the heelshoe, without Vany loose joint or danger of cramping. i

The pitn'ian 1,4 ,is .constructed of aituheof iron or.stecl,=into.which the Jiniiebar pin ,-15. and crank-head 2.0 ere inserted and held-by ofthe finger-,U isformed-.the backward -sloped face 26, which tsin thenobch 27 inthe fingerbnr, and the-finger is fastened, to the finger-.bnr by one or `more screws. or rivets, .asshoxvin which pass through `the finger bnr zuid rear part of the finger.

The grani-shoe W, shown in demiliniFigs. 10, consists of the baseplate 6,1, whchhas a. slot cut through it for the end of the knife-har to ploy in, and the part of the plate 61 above this slot is cnt away in the crescent .'form, 6 0,` shown in pla-n, so as to leave n cover for the brick and front of thcilcnives Without having n large space between the upper sides of the knives and the top of the base-plate i'or the groin or dirt to crowd in und clog tlieknii'e bnr. The grain sidec is arranged on the inside ofthe plate (il, and extends from thepoint of seid plete, as shown in elevation, so es to commencev separating thc grain as soonras the point of the shoe enters it, and to keep it Bepnrnted ns fest es cut unt-i1 received by' the trucker-rods. The standard d is arranged on the. plete 61, als shown, und serves to hold. the tracker-rods 2-1 24, which nreoi'the forni shown, .find nre bent :it right :ingles nt their lower ends, so es to enter the holes in the grain side c, when thev :ire secured in position by dropping thelnoneonto ,the otherbetween-thc side Ac end-,standard has shown in Figs. 1 nndi.

The springyrunner eis ottoched tothe front end of plate Gl, as shown, rind its reniend is hcnt into n. ,C forni, and has the slot d eut in it, tliroi |gli which passes the ;Ldiustiugscrew f, which screws throngh-the=back ofthe plate (il, und has a. bearing on the ,spring-run nerbeloxv, so that seid screw serves both to adjust .the rheight and to steady the springrunner against side motion on the shoe.

The ngcrbnr and couplingi'ru-nie nre raised by the lever Y, pivoted on the side piece if, and provided ,.xxiitlLt-lieeircular segment Xto which .is attached `the chain V, which passes over the pulley u on the side piece k to the staple ic on the coupling-frame. `The ratchet segment tis fixed on the side plete lr, ond thipnu'l s is nrrnnged on the leicrl', So as to lock inthe-reichen@ cud thus hold up the finger b nr. The wire q is attached to t-he puwls, and extends up the side of the lever Y, mound which itis coiled into a handle, r, whiclris slidlnpnnd down by the driverto operaie the Theirods K K, which support the dm'vers seat, areixed in the `pla-tue A, and are coi-rn. gated along Atheir benringiine, :is shown, to p lfient the driigerjssent from sliding on the rods,.except .when desired bythe driver. The seetl is attached-to .thestanda-rd Mreach arm of =whichis ttaohedio `one of the Springs J, which extend across-the machined-eine. Eyes areiormedttheends.Qf these springs, and through theseieyes are passed the .swinging SnppOrtsLL, 4which are bent up et right on gles Vattirersidgesmit" the springsJ J, and here hooks formed nttheir .upper ends, which hook over thegrods d{;K,; thus giving a. swinging Vsupport totheseat, andlessening the shocks due to the vside motions of the machine, as well as enabling' thev driver to vrendily adjust his seat on therodsso as to balance the machine, or to readily removetheseet from the machine by 4simply.unhoolring A-the supports ,-L L from rods K,K, if found desirable.

The rod44 is made in :LU forni, and has the broad treadlebonrd 45 pivot-ed on it, the ends of the rod being hinged in'lngs 46 4G on theiplate A,and one side of the rod resti-ing on the treadie-arm 43 0E the shipping-lever 3,9. The treadlefboard A5 is so situated as to form a coinformblesnpport for the feet 0f the driver in the sent l', who, by placing his feet ou said hoord, forces down the shippingicver 39, and throws the machine iu gear.

When the trouille-board is not wanted, it can be smuig hoek under the drivel-s feet, and the machine con be then thrown in gear by stepping on the treudlearm 43 of the shipping-lever.

The butt/011.42 is pivoted on the ense B, and is inode witlrside nnge S3, (see Figs. l :1nd 7,) or ii'preferred, cnn be :nude of considera..- ble thickness, the object. heilig to nii'ord a. good side beni-ing, so that the driver with his foot cnn turn sind button down so :is to hohl the lever 39 down to hold the machine in ges-r, or can turn said button baolr onto the pin 41 when not in use.

In driving 1u Lv machine on the road, when rigged as a mower, the tingerbnr can be turned up over the tongue in an ordinary manner; but when a platform is attached to the lingerbar, asin reaping, l unhook the rod p from the lever S, and take the pitinan-pin 15 out of the laufe-shank 13, and remove the nut or pin by which the linger-bar heel-shoe is held on the pivots 49, when the finger-bar can be swung 'around into the position slion'nby dotted lines in l l, where it is attached to the machine by the drag-hook 47 which has a pivot end, 4S, which is secured in the bearing l in the heel- Slioe T by the saine nut or pin which was used on the pivot-bearing 4Q, and the hook-part 47 of which hooks over the coupling-bar Q., and is of sulheient breadth to hold the lnger-bar in e. horizontal posit-ion as regards its tipping around its ed ge, the back end of the finger bar being' supported by the casterwheel at the grain side ofthe platform,
